Looks like the unit I was trying to replace, but is not. However, when installing, it did fit and works OK.My old unit had three anchor connection on each side for adjustment when the unit slides. The new unit had only two, but we still made it fit using the two points to anchor the two connecting arms. The screws included with the new unit included a anchor bolt (instead of the bolts on the old unit) and was missing a cotter pin, which I used a wire tie, could have used a nail but decided against. It would have been nice to have instructions or at least a picture on installation for a reclining chair, but the unit could be used for many applications, so they did not have any. The bottom line is, this unit save us from buying another reclining chair for a minimum cost in replace parts. It was just very hard to find the right part from all the options out there. Verifying the two ends for the right anchor points and connections, Number of holes on the sliding plastic block, the proper length of the unit on how they describe the measurements from end to end, the electrical connections and its exit point. You have to use the new wiring system that comes with the new unit.
